如果我理解正确,这就是你想要的:
您可以通过创建一个包含UINavigationController的自定义UIViewController来实现此目的.创建一个名为“CustomViewController”的新类,并粘贴以下代码: 接口 #import <UIKit/UIKit.h> @interface CustomViewController : UIViewController - (id)initWithViewController:(UIViewController*)viewController bottomView:(UIView*)bottomView; @end 执行: #import "CustomViewController.h" @implementation CustomViewController - (id)initWithViewController:(UIViewController*)viewController bottomView:(UIView*)bottomView { self = [super init]; if (self) { // Set up view size for navigationController; use full bounds minus 60pt at the bottom CGRect navigationControllerFrame = self.view.bounds; navigationControllerFrame.size.height -= 60; viewController.view.frame = navigationControllerFrame; // Set up view size for bottomView CGRect bottomViewFrame = CGRectMake(0,self.view.bounds.size.height-60,self.view.bounds.size.width,60); bottomView.frame = bottomViewFrame; // Enable autoresizing for both the navigationController and the bottomView viewController.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; bottomView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin; // Add views as subviews to the current view [self.view addSubview:viewController.view]; [self.view addSubview:bottomView]; } return self; } @end 现在使用CustomViewController: UIView *myBottomView = [[UIView alloc] initWithFrame:CGRectMake(0,200,100)]; myBottomView.backgroundColor = [UIColor redColor]; CustomViewController *customViewController = [[CustomViewController alloc] initWithViewController:<yourNavigationController> bottomView:myView]; (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
